Supporting Videos for Module 3, Day 1 Lecture: Introduction to Cell-Biomaterial Engineering
Slide 6: Cytokines promote cell functions
Chemokinesis control: Naïve T cells in the absence of CCL21 are round and exhibit mostly Brownian motion. (Courtesy of Darrell Irvine. Used with permission.)
Chemokinesis +CCL21: Naïve T cells in the presence of sufficient CCL21 will polarize and migrate along a protein-coated surface. (Courtesy of Darrell Irvine. Used with permission.)

Slide 9: Putting it all together: in vitro construct
Cells in scaffold: Activated T cells are able to migrate through a 3-dimensional porous polymeric scaffold. T cells were stimulated with CCL21 and the polymer was coated with an adhesion protein.
